Steps to reproduce

1. Use the code up to #8009ec commit.
2. Accomplish some task.
3. Leave the game and clear it from recent apps.
4. Try to play again.

Note that this also happened when I updated from the old version to this one. I can't remember if it happened on the previous version, but I think it didn't.

What game mode were you using?

[Lonami]

REDB server game mode, connected to the internet.

[phikal]

I'm sorry, but I can't reproduce it. What device/language are you using?

[Lonami]

I'm using a Sony Xperia M4 Aqua set to English (United Kingdom) under Settings/Language & Input.

Edit: I've tried changing it to Spanish (Spain). Same result (I didn't uninstall or clear application data, it is as it was when this first happened).

[phikal]

I'm not sure about the device, but since I use United Kingdom English too, that shouldn't be the problem.

Do you have root access? And if so, could you post the preferences file (/data/data/com.phikal.regex/shared_prefs/com.phikal.regex_preferences.xml), since line 228, sets what part of the EditText box should be selected. IndexOutOfBoundsException would make be believe, that this selection wasn't saved properly, and therefore provoking the exception.

Edit: Nevermind, I managed to reproduce the bug myself. You just have to select some text, and then leave the app. I'll try and fix it before F-Droid builds the app - thanks for noticing

[Lonami]

Got root?

Never have enough ;) The file looks something like this:

Edit: Oh alright, smart notice! Thank you for fixing it.

Jeez, that's #efficiency, well done 😁
